. Further objects and advantages of the invention will be seen from the following specification and the claims and the accompanying drawings which illustrate a preferred embodiment of the invention.

The machine according to the invention may be advantageously employed for various purposes, however, it is particularly adapted for carrying out a novel method of preparing statements and the like, as described in my copending patent application Ser. No. 550,939, filed July 15th, 1931.

The illustrated embodiment shows in addition to the perforating grammatically the nisms of the machine in accordance with the The accumulator The accumulator mechanism is shown diagrammatically in Fig. 3 in which the accumulator known printing device of wheel is indicated at 82; said wheel is driven by a wheel 82 which may be engaged by means of a coupling linkage 8| with the continuously rotating drive shaft. The clutch linkage 8| is electromagnetically controlled by the accumulator magnet 940 (Fig. 1 of the respective record column, and will be disengaged at the end of the card passage so that the amount corresponding to the perforation will have been entered into the accumulator wheel 82. Simultaneously with the accumulator wheel 82 the cam wheel 84 is rotated by the drive wheel 82, the height of the steps of said cam wheel corresponding to the adjustment of the accumulator wheel 82. The cam wheel 84 is analyzed by means of contact devices 850, 860 (Fig. 3) which in turn control the printing magnets 380 (Fig. 1) in accordance with the adjustment of the accumulator so that the respective total will be printed.

The printing mechanism may be under the control of the record cards for item printing as well as under the control of the aforesaid contact mechanism 850, 860 for total printing. The printing mechanism for one place (corresponding to one record column) is shown in Fig. 2.

From this figure it may be seen that the ends of a reciprocating lever 26 are connected by links 290 with a cross head 30 being movable along vertical bars 3| and receiving a vertical movement by the aforesaid lever 26. head 30 extend arms carrying a cross beam 32 passing through a number of slotted type bars 33; each type bar 33 carries on its head the type 34 being movable in vertical direction and corresponding to the ten numerals 09. The bars I 33 are normally drawn upwardly by spiral springs 350 which are connected to levers 360; consequently the bars 33 are held in engagement with the cross beam 32 and will follow the upward movement of the latter (which the same receives by lever 26) until they are arrested by the pawls 3! which are under the control of magnets 380, said pawls engaging in to the notches 39 of the bars 33. The spacing of the notches 39 corresponds to the spacing of the movable type 34 and the movement of the bars 33 under the influence of lever 26 is effected in synchronism with the passage of the record card under the analyzing brushes; if therefore the brush encounters a hole the coordinated magnet 383 will be energized and thereby the bar 33 will be arrested on a point of its upward movement at which the type corresponding to the perforation is in printing position and the bar will be held there until printing has been effected.

The cross head 30 has rearwardly extending projections with rollers 40 engaging into the slots of levers 4| which are pivotally mounted at 42; if the cross head rises said levers will be pressed rearwardly consequently to the slots and the cross beam 43 will therefore be moved to the left in engagement with the pivotally mounted spring actuated levers 44; the latter will be pressed rearwardly thus moving a number of spring actuated printing hammers 450 away from the type. At the end of the upward movement of the cross head 30, however, the bar 43 will be drawn downwill impel the selected type or an idle type of the type bar against the platen 85. Consequently, the type will print upon the record sheet 46 the numeral corresponding to the perforation.

From the cross 7 For the suppression of zero printing in the places to the left of the highest numeral place and for automatic zero printing in the places to the right therefrom, there is a zero controlling mechanism provided which is shown more in detail in Figs. 2 and 6. This controlling mechanism comprises a lever I20 for each type carrier, said levers being pivotally mounted at I2 I. Each lever has an arm I22 extending over the lever to the left thereof. If the lower ends of the levers I20 catch into a notch I23 of the bars 33 the bars are permitted to move upwardly to a point where an idle type is in printing position; however, if the levers I20 do not engage into said slots the type bars are arrested by a projection I24 in a position being for one unit lower and in this position the type carriers will hold the zero type in printing position so that in all the respective places zeros will be printed. It will be seen that consequently to the superposition of the levers I20 in all places being to the right of the highest numeral place automatically zeros will be printed, in item as well as upon total printing (independently of the control of the type bars by the record cards or by the accumulator) in case there is no other numeral adjusted, and that in places being to the left of the highest numeral place the type bars will be moved to the highest position since in said places the arms I22 are permitted to move freely into the slots I23 so that in said places no printing will be effected at all.

Since the perforating mechanism may be used at will in connection with the printing tabulating machine, at first the operation of the tabulating machine without perforating mechanism shall be described on the circuit diagram and thereafter the perforating mechanism will be described as well as the insertion of its control magnets into the current circuits of the tabulating machine.

By depression of the start key at 510 (Fig. 1) the current circuit will be closed from the main line through the tabulator motor TM, and leading then over the clutch magnet 21, motor relay 80, start contacts 510, motor control relay contacts 11, cam contact 305 (now being closed), cam contact I29 and contacts 550 to the other side of the current source. If only item printing is to be efiected the same current circuit as has been mentioned before will be closed with the only exception that the current will then flow from the cam contacts I29 through the contacts 520 and 540 to the other side of the main line, and the machine is operated at a lower speed. It is to be mentioned that the cam contacts GI, 62, 64 are all controlled in unisonby means of shaft 39 which rotates synchronously with the other parts of the machine. The cam contacts 305 are controlled by shaft 220 rotating synchronously with the shaft 39. The cam I54a for contact I29 is fast upon shaft 900 of the printing mechanism. Consequently, if only the accumulator mechanism is in operation and no item printing is effected, this shaft will be in rest position. It will only be operated upon total printing and resetting of the accumulators. The automatic group control mechanism comprises in the illustrated embodiment four group indicator contacts 48 and a contact 48b; another contact serves to control the control relay II and contact 40 serves'to complete the current circuit if the accumulator is only to be used for group indicating without any automatic group control. The first of the last mentioned contacts energizes relay 1| if all contacts are closed, the relay remaining then closed under the influence of .a

I9 and 20 after the contacts I1 have been closed before by the other card lever I5. If it is now assumed that only'cards belonging all to the same group are running through the machine the controlling holes under the upper and lower brushes will pass at the same time under said brushes. This will establish a current circuit from a lower brush 6 to the contact block II and then through line 69 to the contact block I0 of the corresponding upper brush and from there tobrush 5. The current circuit leads from the upper brush to the plug contact 10 of the plug board; for reasons of clarity the plug connections which are normally to be made are not shown in the diagram. The current may then flow through one of the control magnets 29 back to the current source; the energized control magnet interrupts the contacts 35, 36 to take the spark from the brushes and simultaneously the contacts 38 will be 'closed which complete a part of the shunt circuit including the control relay I I. The same operations will take place during the passage of the remaining record columns at the brushes being inserted into the group controlling circuit so that 2 the shunt circuit will be completed. During the machine cycle the cam contacts 64 are instantaneously opened which has, however, no effect upon the relay II since the current circuit 13 is still closed by contacts 38 while in the other case the current circuit of the relay would be interrupted. The plug 303 may be inserted into any one of the contacts 304 in order to exclude one or a plurality of control circuits if less than the total number of the existing group control units are required.

At the end of the passage of the first card under the lower brushes the cam controlled contacts 630 will be closed thereby causing a current impulse through the group indicator magnet a which releases a lever not shown in the drawings and permits a bar to open all contacts 48 as long as the card run through the machine is not interrupted so that said contacts will remain open.

It is still to be mentioned that the group indicator contacts 48 are inserted between the points 14 and 15 to prevent entering of group data of the following cards into the accumulator after the group number has once been entered into the accumulator from the first card.

From the foregoing it will be seen that the group controllingcircuit remains closed as long as subsequent cards are in agreement and consequently the machine will continue in its operations. If it is now assumed that the last card of a group has passed under the upper brushes and is about to come under the lower brushes, the first card of the following group will be under the upper brushes; since both cards are provided with different group numbers the aforesaid controlling circuit will be interrupted between the upper brushes 5 and block I0 thereby interrupting also the current circuit 69 and preventing energization of magnets 29. Consequently, the contact 38 and the current circuit I3 will remain open so that upon opening of contacts 64 the relay II will be deenergized and will interrupt the current circuit of motor relay I6, thereby opening the contacts 11. These contacts are in shunt to the circuit 18 and are inserted in mere tabulating operations (only accumulating and total printing) over cam contacts MI and upon total printing over cam contacts 19; said contacts open at the end of the machine cycle and consequently the motor relay 80 and also clutch magnet 27 will be deenergized so that the machine will be stopped.

If total taking is to be efl'ected manually, the switch I08 (as shown in the drawings) must be opened and the reset key 580 must be depressed. Then a current will flow from the current source 590 through contacts 550 (in tabulating operations) or contacts 540, 520 (upon item printing), then through contacts I29 now being closed, through the various lines to the reset key 580, the contacts Ia now closing, the clutch magnet controlled contacts 96, reset magnet 620, reset motor 600 to the other side or the main line and back to the current source. The cam contacts I00a, I and 630 are provided upon a shaft rotating synchronously with the shafts 39 and 220. The reset motor 600 causes printing of the total and resetting of the selected accumulators as is usual in tabulating machines. After total taking and resetting has been initiated by the reset key 580, the current is taken over from the reset motor by a relay controlled magnet 620 short circuiting the reset key 580. After total taking and resetting the magnet 620 will be short circuited. The control of the printing and resetting motor is governed by contacts I40 being provided upon shaft 900 rotating once during the printing and resetting cycle. Said contacts open at the end of the printing and resetting cycle the current circuit to the motor 600 and prevent thereby further rotation of the same. The means to take at first the total and then reset the accumulators are controlled by magnet 520 as is explained in prior patents. It is still to be mentioned that the contacts 96 prevent printing and resetting if the tabulating motor TM is running and has energized the clutch magnet which opens the contacts 96.

If the total is to be taken automatically the switch I08 must be closed. Then the contacts I05 which initiate printing and resetting will be closed (just before the machine is stopped automatically under the control of the group controlling mechanism) and printing and resetting will then be efiected in the above described way. The current circuit of the switch I06 extends over the contacts which are under the control of stop key 560; if therefore said contacts are open total taking cannot be automatically initiated.

After a total has been taken either automatically or by key actuation, restarting of the machine for the next card group may be effected either automatically or manually. For the manual release only the start key 510 must be depressed thereby initiating another machine cycle as has been described. In order to effect an automatic restart of the machine the total switch I30 must have been closed before. Over said switch will another start circuit be closed as follows: From the current source 590 through tabulating motor TM, clutch magnet 21, motor relay 80, switch I30, cam contacts I28 being closed at the end of the printing and resetting cycle by the cam I54, around motor relay 80, through the lower card lever contact (now being closed since there are cards in the machine), through motor relay controlled contacts 11 (now being closed) then either through cam contact 305 or interruptor contacts to the cam contacts I29 (now being closed), through one of the contacts 550 or 520/540 to the other side of the line and back to the current source. Said current circuit will automatically initiate another machine cycle. The machine will then continue in its operations since the contacts of motor relay 80 remain closed until they are opened again at the end of the next card group under the influence of the automatic group control mechanism, whereupon total taking, resetting and restarting of the machine may again be initiated in any one of the above described manners.

If the card supply is exhausted, accumulation of the data of the last card will be completed in the known way and then total taking will be effected; this, however, needs no further explanation in connection with the present invention since the respective operations are described in the above mentioned prior patents. The cam contacts 630 serve to release the current impulse to the group indicator magnets 45 at the proper moment in the machine cycle. The cam contacts I serve for the control of the current supply to the current circuits 22I leading to the total taking contacts 850 and 860 which are controlled in the known way by the cam disks 84; the printing magnets 380 are in series with the contacts 860.

To control printing of the total from any of the accumulators at will, there are provided three contacts I08, I01 and I39 which are controlled by levers I43. If said contacts are open the printing current circuits of the coordinated accumulators will be interrupted thereby preventing total taking. If it is desirable to switch off simultaneously all total taking magnets the switch 309 can be opened thereby interrupting the current circuit of the cam contacts I25. In the present embodiment the printing magnets are permanently in series with the accumulator magnets 940 and if a controlling impulse is released both magnets will be energized simultaneously. The adjustment of the machine either for item printing and accumulation or accumulation only may be controlled by a special lever which controls also the drive mechanism of the machine. I

This mechanism as well as further details are, however, clearly described in the prior patents so that no further explanation is necessary in the present specification.

The switch 302 shown in the diagram serves to close a current circuit which prevents in any way automatic group control; this is desired if the machine shall only accumulate the data or if only item printing shall be effected independently of the group designations of the cards.

The switches 3I0 and 3I I serve to permit tabulation if they are closed; if the switch 302 is closed the automatic group control mechanism is switched off. If the switch 302 is open as illustrated and switch 3I0 is closed, group control will be eiTected in the record columns coordinated to the accumulator as far as corresponding switch connections have been made.

In a printing tabulating machine the accumulator wheels control total taking while item printing is effected by record cards. The accumulator magnets 940 which are energized by the holes and which are adapted to engage the accumulator wheels close a shunt circuit about the brushes over the contacts 3II. This is for a double purpose, on the one hand to take the spark from the lower brush 6, and on the other hand to maintain the current circuit through the accumulator magnet 949 and the printing magnet 399. If now the automatic group control is used the same devices are used. By energization of the magnets 940 the main current circuit of the through the holes of the upper card are prevented.

To the contacts I08, I91 and I39 for the selective control of total printing from the various accumulators are bell crank levers I43 coordinated; said levers are under the control of the reset clutches as has been described in the above mentioned prior patents. If the reset clutch of any accumulator is moved to the left, resetting of the corresponding accumulator will be prevented by simultaneously opening the coordinated contact IDB, I01 or I39, and accordingly also total taking from the respective accumulator which is not reset will be prevented. If on the other hand the clutch member is adjusted in the right hand position, the accumulator will be reset and the corresponding switch will be closed so that also a total will be taken from said accumulator. In

the generally known way provision may also be made to take a total without resetting the accumulator.

Now, reference will still be had to a few general operations of the machine: If the machine is to be used only for mere accumulating (without printing any items) the tabulator will operate in the-usua1 way with a higher speed, and by means of the shiftable speed mechanism the contacts 520/540 will be opened. At the same time, the operator of the machine will open the switch 399 which prevents total printing. The machine may then operate as ordinary computing machine and the printing mechanism will be idle during the accumulation. Upon resetting, the printing mechanism will perform one cycle, but since the total taking circuits are not closed no printing will be effected.

If it is desirable to accumulate the data of each card group and to print the total of each group, the switch 309 must be closed so that total printing at the end of each card group will be permitted. During such accumulating operations, item printing will be entirely suppressed and during the printing operations only the total of the previously accumulated items and the coordinated group number will be printed.

The above described manner of operation may be performed'either fullor semi-automatically. So for instance the data of a stack of cards may be accumulated and if the switch 392 for the automatic group control is open the accumulation will be automatically interrupted if the card group changes. Total taking may then be initiated manually by depressing the key 530 or automatically (-if the switch I06 has been previously closed.) After total taking (either automatically or manually) the tabulating machine m y be restarted either automatically or manually. In the latter case it is only necessary to depress the start key 519 while in order to cause automatic restart the switch I30 must have been clo"ed. If said switch is in closed position the initiation of another machine cycle will be automatically effected by the cam contact devices.

If. it is desirable to print items, the printing mechanism is rendered operative through the printing lever as has been described in the prior patents. Simultaneously therewith the speed control mechanisms will be shifted so that the corresponding contacts will be opened and this will cause operation of the tabulator with a lower speed. It is then possible to print the various items and to accumulate the same as well as to print the respective totals. It will be seen that the group numbers serve for the control of the operation of the machine and also for the control of total taking and that in the described embodiment they are not entered into the accumulator from each card; the group number is printed adjacent the first item and then no further printing will take place until the total is taken when the group number will again be printed adjacent the total. The group number may, however, also be printed to each individual item, but then the group indicator contacts 49 are not inserted into the analyzing circuit;

with this manner of operation the group number will not be printed together with the total.

The perforating mechanism which is provided according to the present invention in the tabulating machine, comprises a number of perforation units, one unit being provided for each record column to be punched as is for instance shown in Fig. 5. From Figs. 5 and 9 may be seen that at the one end (preferably at the left end) of the printing roller 85 there is a groove provided in said roller in which a matrix block 9| is located; the latter is rigldlyconnected to a holder 81 in such a way that the inner stump of the platen is permitted to revolve freely in the boring between 9| and 81. The holder 81 is rigidly connected by a bar 88 with a plate 99 being connected to the bearing I10 of the platen; to the plate 99 is fastened also the punch carrier 23. It will be seen that the record sheet 46 is free to move between the punch carrier 23 and the matrix block 9|. Through the punch carrier 23 passes a guide bar of the guide rollers 89 for the record sheet and similar guide rollers are provided above and below the platen at both sides of the punching mechanism so that the record sheet is fed safely by the rotating platen between the fixed matrix block 9| and the punch carrier. The matrix block 9| has a hollow space 92 extending axially to the platen over all rows of punching stamps and terminating into a pipe 92' being preferably connected to an exhaust line operated by a ventilator or the like in order to remove the waste from the space 92. The punch carrier 23 comprises for each record column four resiliently mounted punching stamps 93 being symmetrically arranged above and below the printing line and being normally held by a cover plate 94 in the position shown in the drawings. The punching stamps 93 are slotted at their outer ends and into said slots engage pivotally mounted levers 95 being connected with slides 96 which extend through the guide plate 25 of the punching stamp case 24 to the outside of said plate. The distance of the slides 96 from each other corresponds exactly to the distance of the notches 39 of the punching stamp carrier bar 33', 5|, 52 and the notches 39 in turn correspond exactly to the similar notches of the type bar shown in Fig. 2. For the representation of a certain numeral the punching stamps 93 are depressed by means of the slides 96 either singly or in different combinations in order to punch a hole combination into the record sheet 46. The selection of the punching stamps is effected in according with the numeral to be punched in a similar way as the selection of the printing type in Fig. 2. For each record column there is a notched bar 33' provided which is drawn upwardly by means of spring 356 in a similar way as the type bar of the printing mechanism in Fig. 2; each punch bar may be arrested in different positions by the pawl 31 under the control of the selector magnet 60. The bar 33 is connected with the bar 52 by a cross piece 5I and the bar 52 carries four resiliently mounted pins 53 which are spaced as shown in the drawings. If the bar 52, 33' is in the lowermost position, the uppermost pin 53 is just for one tooth 39 below the lowermost slide 96, and if the bar 52 is in its uppermost position (the lowermost and uppermost positions are indicated by dotted lines) the lowermost pin is for one tooth 39 above the uppermost slide 96. In all intermediate positions, however, one or a plurality of the pins 53 will be adjusted opposite the slides 96v and if then in the way still to be described the plate 58 is moved to the right, the selected punching stamp or punching stamps 93 respectively will be pressed under the control of the pins 53 and the slides I36, 95 through the record sheet 46, and upon return movement of the plate 58 the punches will also return under the influence of their springs to their home position. The perforation scheme with respect to the various positions of the bar 33 may be clearly seen from Fig. '7 and may be verified on Fig. 5; in said Fig. 5 is the punching bar so adjusted that the numeral 5 will be punched, in accordance with Fig. 2 in which the type 5 is in printing position. For reasons of clarity it is still to be mentioned that the hole positions pass in the sequence of 9 to 6 under the brush and that consequently also the type and punching stamp bars rise in the same sequence from the lowermost to the uppermost position through the various numerical positious. The adjustment of the selector bar 33 is effected by the selector magnet 60. During the machine cycle the type bars 30 (Fig. 2) and simultaneously therewith also the punching bars 33' are raised by the same mechanism which has been previously described. At the end of the machine cycle, and in the same moment in which in the printing mechanism the type hammers are impelled towards the record sheet, the points of two earns 56 rotating once during each ma chine cycle will encounter the fingers 51 of a frame 58 being guided upon pins of the casing, said frame being normally held by springs 55 in engagement with the cam disks 56. The points of the cams 56 will move the frame 56 and the pins 53 lying just opposite said frame to the right, and consequently also the slides 96 and levers 95 will be moved far enough to press the corresponding punching stamps 93 through the record sheet 46 while all other punching stamps, i. e. those punching stamps to which no pins 53 are coordinated between their slides 96 and the plate 58 will be inoperative and no perforation will be caused thereby. After perforation has been effected and printing has taken place in the previously described way, all parts will return to their home positions and consequently also the punching bars 52, 33' will return under the influence of the cross head 30 to their home positions.

Controlling of zero punching upon item perforation as well as upon perforation of a number under the control of the accumulator is 81- fected (in a similar way as has been already explained in connection with the type bar) by means of a pivotally mounted lever I20 encountering either a recess I23 or a projection I24. Consequently, in all places being to the right of the highest numerical place the zeros will be automatically punched while in all places to the left thereof the bars 52 will raise for one unit higher so that the lowermost pin 53 moves beyond the uppermost slide 96 and consequently no perforation will be effected at all in the respective punching column.

The distance of the perforation from the side edge of the record sheet determines the denominational value of said perforation, however, the meaning of the perforation is not yet unequivocally determined. For this purpose there is a special standard point punching stamp provided which produces each time a record perforation is effected a hole on the same predetermined position which hole is invariably at the level of the lowermost hole position of the record perforation and which is therefore adapted to determine the meaning of the hole combinational records. The device for producing the standard point hole may be seen from Figs. 5 and 8. On opposite side walls of the casing are two bell crank levers I66 (in the drawings is only the lever lying on the one side shown) pivotally mounted which are connected with one another by a cross bar I6I which is normally drawn by a spring I63 against the left edge of the bars 52. Each bar 52 has a recess 54 which is just opposite the yoke I6I if the bar 52 is in its uppermost position (i. e. for one step above the zero position). The recesses 54 of all perforation bars 52 will therefore be just opposite the yoke I 6| if all bars 52 are in their uppermost position, i. e. if no record perforation will be effected at all. In this instance the spring I63 will draw the yoke I6I into the recesses 54 and consequently the bell crank levers I60 will be rocked so that also (see Fig. 8) the arm I62 will be drawn downwardly and the arm I 64 connected therewith by a pin and slot connection will be moved downwardly. Said arm I64 as well as the arm I62 are, of course, to the left of the extreme left punching column; the arm I64 is pivotally connected with the punching plate 58 and lies normally opposite of a slide I66 adapted to cooperate with the standard point hole punching stamp I61.

The cams 56 rotate, of course, only during printing cycles so that only then a perforation will be effected provided the bars 52 are adjusted in punching position. If now for instance in connection with total taking no perforation shall be effected the selector magnets 60 will not be energized and all bars 52 will raise to their uppermost position so that in each of such cycles the arm I64 (Fig. 8) is rocked lower than the slide I66; consequently, if the bars 52 are in their uppermost positions there will be neither a record perforation nor a standard point hole perforation effected; however, if through one or a plurality of the bars 52 a record perforation is effected, the lever I60 is prevented from rocking in a clockwise direction so that simultaneously with each movement of the plate 58 to effect a record perforation also a standard point hole will be punched.

As will still be explained, with group accounts and printing of each individual item, the group designations are usually punched only to the first item of each group so that in such accounts the space required for the perforations needs no particular consideration since said group ac counts require in any way a longer record sheet than is required for the perforation. However, if only totals are to be printed or if a perforation shall be entered to each item the record sheet must receive larger feed steps since the perforation requires a larger space in vertical direction than the printing line. The device serving for this purpose is shown in Fig. 10 showing the device adjusted for normal linewise typeprinting. The lever I55 having a projection I55 is raised synchronously with the printing mechanism,

rocking thereby a lever I52 which is pivotally mounted at I53 and which engages with its pin I5Iinto a slot I50 of a lever I48 pivotally mounted upon the shaft- 86 of the printing platen and being normally drawn upwardly by a strong spring I45. At the left end of the lever I48 is a shift pawl I44 pivotally mounted engaging with a sidewardly extending projection into the teeth of the ratchet wheel I41 being fast to the platen roller and being held in its position by the bell crank lever I46. If the lever I48 is rocked in clockwise direction consequently to the raising of bar I56 (turning thereby the pawl I44 for the amount of three teeth) the roller I45 of the shift pawl I44 will encounter a plate I40 and will thereby be moved out of engagement with the ratchet wheel. Upon the return movement of the arm I56 the pawl I44 will be moved downwardly under the influence of spring I49; however, the roller I45 will slide upon the plate I40 long enough so that the shift pawl will skip two teeth and will engage only the third tooth thereby effecting a shift step corresponding only to the length of one tooth which corresponds just to the normal distance between two printing lines. This adjustment of the record sheet feed mechanism is for instance used in connection with the above mentioned group accounts. However, if a perforation has to be effected to each printing line the plate I40 is adjusted in the position shown in Fig. 10 in dotted lines and is secured by means of the set screw MI. The pawl I44 will then be in engagement with the ratchet wheel during the whole backward stroke of the lever I48 and consequently the pawl will rotate the platen for three teeth thereby effecting a sufficient distance between the various record lines and providing a suitable blank space between the various perforations coordinated to the printed lines.

Now the various manners of operation in connection with perforation shall be described with reference to the circuit diagram-of Fig. 1.

If it is desirable to punch to each item the identification represented in a certain hole field of the record card, such as for instance the account number, the selector magnets 60 are inserted immediately between the plug contacts 14 'and 15 so that the magnets are from the analyztotal punching will usually not be effected; however, the total may be taken from the accumulators and punched in the above described way without difficulty. In this case, the selection and adjustment of the various switches of the tabulating machine must be effected in the known way for item printing so that the various items will be printed and a perforation will be entered to each item in the above dwcribed way, said perforation corresponding the the perforation of the record field selected for said purpose, with the only difference that the respective number is represented upon the card according to the single hole system while the perforation upon the record sheet is effected according the hole combinational system; it will, of course, be understood that the invention is independent of the system of perforation.

If group accounts are to be made by means of the automatic group control mechanism it may be desirable to punch the identification or group designation to the first item of each group but to suppress the perforation for each following item of the same group. Further, it may be desirable to print to the first item (in addition to the perforation) the group number as well as to all other items, or to print said group number only to the first item. In the latter instance (i. e. that the group number is to be punched and printed only in connection with the first item) the magnets 60 and the group indicator contacts 48 must be inserted between the plugs I4 and 15, the magnets 80 lying in series with the contacts 48. After the passage of the first card the selector magnets and the printing magnets are switched off from the analyzing brushes due to the interruption of the contacts 48, after the group number has been entered into the accumulator by means of magnets 940. With the following items there will be no printing of the group number and also no perforation of the same, and only upon total taking the group number which has been entered into the accumulator will again be printed by the printing magnets but it will not be punched in the present instance. If it is desirable to print the group number to each item, to punch, however, said number only to the first item of each group, the magnets and contacts 48 are switched in series between the plug contacts 98 and 15. This will cause that after the passage of the first card consequently to the interruption of the group indicator contacts 48 the magnets 60 will be switched off from the current circuit, and consequently no perforation can be effected during the following Items. Simultaneously with the aforesaid switch connection, however, also a direct connection must be made between the contacts I4 and 15 so that the group numbers are entered each time into the printing mechanism and are printed to each item. Also in this instance the group number will normally not be printed together with the total.

Another manner of operation consists therein that all items are only accumulated (but not printed) and then only the total of each group of items may be printed. In this instance it may be desirable that the group number be also punched to the total and, if desirable, the group number may also be printed. For this purpose the magnets 60 are connected parallelly to the printing magnets 380 directly to the plug contacts 99; the group indicator contacts 48 are switched between the plug contacts 14 and 15 so that the group number of the first card is entered into the accumulator and remains adjusted in the same. cumulation of the data of the subsequent cards of a group the printing mechanism will not be During the following ac-' actuated, and if then upon total taking the printing magnets 380 are energized in accordance with the adjustment of the accumulator, the parallelly arranged selector magnets 60 will be energized simultaneously with the magnets controlling printing of the group indication so that the group number will be perforated as well as printed. If it should be desirable to punch the group number without printing the same it is only necessary to exclude the magnets 380 and insert in place thereof the selector magnets 60. Punching of the group number in totalling operations is, of course, not restricted to the above described ways. It is also possible, as in known tabulating machines, to print the group number under the immediate control of the first card and to punch the same, and then entering the total after completion of the group accumulation. If this manner of operation is chosen it is only necessary to switch the magnets 60 and contacts 48 in series between the plugs 14 and 15.

By means of the above described machine, of course, group accounts of the described kind may also be made without printing the total to each group. For this purpose the group control mechanism is rendered operative and the total taking switches are opened so that only the items of each group will be printed. As has been mentioned above in connection with total printing in group accounts, it is also possible in preparing group accounts without total printing, to punch the group number to the first item of each group and to print the same in addition to said perforation either only to the first item or to all items of the respective group.
